Paper Abstract:
|
Network operators and administrators have been struggling to monitor and analyze the performance of large areas on Software-Defined-Networks (SDN) and single-controller architectures in particular. In recent years, increasing research efforts have addressed modeling, simulation and communications issues regarding SDN. However, most of them presents insufficient details about how gathered data is treated quite often authors does not employ strong statistical tests towards a reliable treatment of the experimental data or even a premise of a formal scientific experiment (with hypotheses tests, experimental design and observation of reliable statistical evidences). In this sense, this paper presents an in-depth experimental study to evaluate the impact of the geographical distance on communication between groups of hosts and a single OpenFlow controller at SDN OS3E topology. A priori results show with a high statistical confidence level that the OS3E area that contains the controller does not present best performance round-trip-time indicators. |
